User-facing copy + brand updates landed together:
- Page H1 + browser-tab title: "DataTools — Data Cleaning Mastery"
→ "UNALOGIX DataTools". Same change in es.json (was "DataTools —
Maestría en limpieza de datos").
- Hero subtitle: long descriptive caption replaced with the tagline
"Clean. Normalize. Transform." (es: "Limpia. Normaliza.
Transforma.").
- Sidebar brand block: wordmark is now two lines — UNALOGIX in tiny
uppercase tracked eyebrow style on top, DataTools in the 15px
semibold wordmark beneath. The 28px "D" chip stays as the
recognizable mark. New ``.dt-brand-eyebrow`` rule in
``_DESIGN_TOKENS_CSS``.
Top-right Streamlit chrome cleanup — the user reported two stacked
icon buttons. ``.streamlit/config.toml`` bumped to
``toolbarMode = "viewer"`` (most aggressive — suppresses status
indicator + deploy button + running glyph). CSS belt-and-suspenders
hides ``stToolbar``, ``stToolbarActions``, ``stStatusWidget``,
``stDecoration`` for newer Streamlit releases that keep emitting
these with inline styles even under toolbarMode=viewer.

Lifts ideas from the ``datatools_layout_redesign.html`` mockup
(artistic licence, not literal). Two changes:
1. ``.streamlit/config.toml`` ``[theme]`` block — cream paper bg
(#fafaf7), warm sidebar (#f5f4ef), stone ink (#1c1917), burnt
orange primary (#c2410c). Streamlit threads these through its
chrome (focus rings, file-uploader accents, link colors).
2. ``_DESIGN_TOKENS_CSS`` injected by ``hide_streamlit_chrome`` on
every page. Imports Fraunces (display serif), Geist (body sans),
Geist Mono. Restyles, scoped through ``--dt-*`` custom properties:
- Page surface + sidebar — warm cream backgrounds, soft warm
borders, no harsh white.
- Sidebar nav — section labels in tiny uppercase tracking, nav
items with soft hover, active item as a white pill with subtle
shadow.
- Typography — H1/H2/H3 in Fraunces with tightened tracking;
body Geist; inline code Geist Mono with orange-on-cream chip.
- Buttons — primary = dark ink (``#1c1917``) with white text;
secondary = paper surface with warm border; disabled = muted
cream.
- Containers / expanders — editorial cards: 14px radius, 1px
warm border, faint shadow, warm-cream summary headers.
- File uploader — cream dropzone with dashed border + per-file
paper chips.
- Alerts — soft tinted fills (info=sky, success=mint, warn=amber,
error=rose) over the kind-specific palette.
- Inputs, tabs, dataframes — paper surfaces with rounded warm
borders.
Verified at 1920x1050 + 1400x900 on home page (empty + with file
uploaded + with findings rendered) and Clean Text tool page; no
regressions in the white-bar fix from 65b663b.

Streamlit's default file_uploader footer reads "Limit 200MB per file —
CSV, TSV, XLSX, XLS" which contradicts the 1 GB efficiency target shipped
in 438bc0f and codified in docs/REQUIREMENTS.md §1.1.
Three changes:
1. .streamlit/config.toml — set [server] maxUploadSize = 1024. Footer
now reads "Limit 1024MB per file".
2. upload_and_analyze_section (home page) — adds an explicit caption
above the uploader stating size limit, supported formats, the four
auto-detected delimiters, and the 13 auto-detected encodings (with
the Review-page override as the safety net).
3. pickup_or_upload (every tool page that falls back to its own
uploader when no home-page upload is present) — same caption,
only rendered when the upload accepts CSV/TSV/XLSX/XLS so JSON
schema / config uploaders aren't decorated.
Test suite: 765 passed, 17 xfailed (no regressions). Home + Review +
Deduplicator pages all serve HTTP 200 under the new config.

Add shared hide_streamlit_chrome() helper that removes header bar,
hamburger menu, footer, and deploy button via CSS injection. Called
on every page. Add .streamlit/config.toml with minimal toolbar mode.
